Description

Caja de cartón apilable.Stackable cardboard box.

Object of the invention

La presente invención se refiere a una caja para productos hortofrutícolas y similares, del tipo de las destinadas a quedar apiladas en agrupaciones verticales de las mismas.The present invention relates to a box for horticultural and similar products, of the type intended for be stacked in vertical groupings thereof.

El objeto de la invención es proporcionar una caja de cartón con una gran rigidez estructural, que optimice las propiedades de apilamiento de la misma.The object of the invention is to provide a cardboard box with great structural rigidity, which optimizes the stacking properties thereof.

Background of the invention

Son conocidas multitud de cajas o bandejas de cartón que comprenden un cuerpo laminar en el que se define un sector central y principal, determinante del fondo de la caja, de cuyos extremos emergen sendas gualderas y testeros que se fijan entre sí mediante encolado, a través de aletas prolongación de uno de estos dos elementos.They are known many boxes or trays of cardboard comprising a laminar body in which a central and main sector, determinant of the fund of the box, of whose ends emerge gualdera and testeros paths that are fixed each other by gluing, through fins extending one of these two elements.

En el caso de que las cajas estén destinadas a ser apiladas, es necesario dar mayor rigidez a la estructura de la caja, para lo cual es habitual que la aleta de fijación entre gualderas y testeros se fije entre los mismos formando un chaflán interior, determinante de una columna prismática de rigidización de la caja, que mejora sustancialmente las propiedades de apilamiento de la caja.In the event that the boxes are intended for be stacked, it is necessary to give greater rigidity to the structure of the box, for which it is usual that the fixing fin between gualderas and testeros set between them forming a chamfer interior, determining a stiffening prismatic column of the box, which substantially improves stacking properties from the box.

Para mejorar dichas propiedades de apilamiento es habitual que dicha columna prismática incorpore unas pequeñas pestañas sobre su extremidad superior, concretamente en la cara determinante del citado chaflán, destinadas a encajarse en ranuras formal y dimensionalmente adecuadas establecidas sobre el fondo de la caja establecida superiormente.To improve said stacking properties it is usual that said prismatic column incorporates small eyelashes on your upper limb, specifically on the face determinant of said chamfer, intended to fit into slots formally and dimensionally appropriate established on the merits of the box established above.

El problema que presentan este tipo de cajas es que dichas pestañas, merced a la propia estructuración de la caja, deben ser de dimensiones muy reducidas, concretamente con una altura máxima que no sobrepase en grosor del propio cuerpo laminar constitutivo de la caja, ya que de ser mayor magnitud que éste, en el apilamiento, al insertarse dichas pestañas sobre las correspondientes ranuras, entrarían en contacto con la base del cuerpo determinante del chaflán del que forman prolongación, impidiendo una mayor penetración, y limitando las propiedades de apilamiento de la caja.The problem with these types of boxes is that these tabs, thanks to the proper structuring of the box, they must be of very small dimensions, specifically with a maximum height that does not exceed the thickness of the laminar body itself constitutive of the box, since being larger than this, in the stacking, when said tabs are inserted on the corresponding slots, would come into contact with the base of the chamfer determining body of which they form extension, preventing further penetration, and limiting the properties of box stacking.

Description of the invention

La caja que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, proporcionando unos medios de acoplamiento entre cajas que hacen el apilamiento entre éstas mucho más seguro, todo ello merced a una simple estructuración, pero de gran eficacia.The box that the invention proposes resolves from the problem was fully satisfactory before exposed, providing coupling means between boxes that make stacking between them much safer, all of it thanks to a simple structuring, but of great efficiency.

Para ello, y a partir de la estructuración convencional anteriormente descrita, la caja de la invención centra sus características en el hecho de que las pestañas de acoplamiento entre cajas en su apilamiento, en lugar de situarse a modo de prolongación del tabique rigidizador determinante del chaflán interno que se establece entre gualderas y testeros, se establecen sobre respectivas aletas que emergen de los testeros en contraposición a las aletas determinantes del tabique rigidizador de la caja en el apilamiento, afectando únicamente a la parte superior de dicho testero, aletas que constituyen los medios de estabilización de dicho tabique rigidizador y que se fijan mediante adhesivo al mismo en su zona superior, de manera que quedan dispuestas paralelamente al mismo.To do this, and from the structuring Conventionally described above, the box of the invention centers its features in the fact that the coupling tabs between boxes in their stacking, instead of being placed as a chamfer determining stiffening partition extension internal that is established between wards and testeros, are established on respective fins that emerge from the heads in contraposition to the fins determining the stiffening partition of the box in the stack, affecting only the upper part of said testero, fins that constitute the means of stabilization of said stiffening partition and which are fixed by adhesive to it in its upper area, so that they remain arranged parallel to it.

Así pues, y como es evidente, las ranuras para inserción de las citadas pestañas no se situarán como es convencional en la zona de la base sobre la que apoya el chaflán o aleta rigidizadora, sino inmediatamente a continuación de esta zona, paralelamente a la misma, en orden a permitir el paso de las citadas pestañas hacia el interior de la caja situada inmediatamente superior, pestañas que presentarán una mayor altura que las convencionales, de manera que tras atravesar el fondo de la caja apoyan sobre los chaflanes o tabiques rigidizadores y consecuentemente determinan unos medios de acoplamiento entre cajas mucho mas seguros.So, and as is evident, the slots for insertion of the mentioned tabs will not be placed as is conventional in the area of the base on which the chamfer rests or stiffening fin, but immediately after this zone, parallel to it, in order to allow the passage of said tabs inside the box located immediately superior, eyelashes that will have a greater height than the conventional ones, so that after crossing the bottom of the box rest on the chamfers or stiffeners and consequently they determine coupling means between boxes much safer.

De acuerdo con otra de las características de la invención, se ha previsto que la aleta que se fija sobre el tabique rigidizador presente un contorno inferior oblicuo, en orden a proporcionar una mayor superficie de contacto en la fijación por adhesivo de ésta pieza al tabique rigidizador, aportando mayor robustez a la caja.According to another of the characteristics of the invention, it is provided that the fin that is fixed on the partition stiffener has an oblique lower contour, in order to provide a larger contact surface in the fixation by adhesive of this piece to the stiffener partition, providing greater robustness to the box.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas, y en especial de la figura 1, puede observarse como la caja que se preconiza, está constituida, como es convencional, a partir de un cuerpo laminar de cartón, en el que se define un sector mayoritario y principal (1), rectangular, determinante del fondo de la caja, del que emergen respectivas gualderas (2-2') y testeros (3-3'), siendo los testeros (3-3') de mayor altura que las gualderas (2-2'), y prolongándose en aletas (4) que mediante líneas de plegado (5) determinan en el armado de la caja un prisma de base triangular-recta, tal y como puede observarse en la figura 2, prisma en el que una de sus caras viene definida por el propio testero (3-3'), otra de ellas (6) determina la superficie de fijación entre testero (3-3') y gualdera (2-2'), y una última cara, que se corresponde con la propia referencia (4), determinante de un tabique rigidizador en el apilamiento entre cajas.In view of the figures outlined, and in special figure 1, can be seen as the box that advocates, is constituted, as is conventional, from a cardboard sheet body, in which a majority sector is defined and main (1), rectangular, determinant of the bottom of the box, from which respective gualderas (2-2 ') emerge and testeros (3-3 '), being the testeros (3-3 ') taller than the gualderas (2-2 '), and extending into fins (4) that by fold lines (5) determine a prism in the case assembly triangular-straight base, as you can observed in figure 2, prism in which one of its faces comes defined by the testator himself (3-3 '), another one of them (6) determine the fixing surface between the tester (3-3 ') and gualdera (2-2'), and a last face, which corresponds to the reference itself (4), determinant of a stiffening partition in the stacking between boxes

Dicho tabique rigidizador (4) se fija al testero (3-3') mediante aletas (7) que emergen opuestamente de los testeros, como también es convencional.Said stiffener partition (4) is fixed to the tester (3-3 ') by fins (7) that emerge opposite of the testeros, as is also conventional.

Pues bien, a partir de la estructuración básica anteriormente descrita, la invención centra sus características en el hecho de que las aletas (7) de fijación al tabique rigidizador (4) presentan una configuración trapezoidal recta invertida, tal y como puede observarse en la figura 1, que como anteriormente se ha dicho constituye una mayor superficie de fijación entre ambos elementos, con la especial particularidad de que sobre el borde superior de las mismas se establecen sendas pestañas (8), de altura considerablemente mayor a la del espesor del cuerpo laminar determinante de la caja, pestañas que en el armado de la caja quedan dispuestas paralelamente al tabique rigidizador (4), de manera que en el apilamiento entre cajas son pasantes a través de ranuras (9) operativamente establecidas sobre el fondo de la caja, apoyando una de sus caras sobre el citado tabique (4), lo que las convierte en unos medios de acoplamiento entre cajas en su apilamiento sumamente eficaces.Well, from the basic structuring previously described, the invention focuses its characteristics on the fact that the fixing fins (7) to the stiffening partition (4) have an inverted straight trapezoidal configuration, such and as can be seen in figure 1, which as previously said constitutes a greater fixing surface between both elements, with the special feature that on the edge top of them are established eyelashes (8), height considerably greater than the thickness of the laminar body determinant of the box, tabs that remain in the box assembly arranged parallel to the stiffening partition (4), so that in the stacking between boxes are through slots (9) operatively established on the bottom of the box, supporting a of their faces on the said partition (4), which makes them coupling means between boxes in their stacking extremely effective.
